PRINTERS QUOIN.

Specification of Letters Patent. Patented 26,

Applicationfiled June 15, 1917. Serial No. 17.4;852.

r '0 old w/wm it may concern:

Be it known that we, Armani? Lanes, a citizen of the United States, and resident of the borough of Bronx, coimty of Bronx, city and State of New York, and ADAlvi Mn'rzecn, a citizen of the United States, and resident of the borough of Bronx, countyof Bronx, city and State of New York, have invented certain new and useful Improvements in Printers Quoins, of which the fol lowing is a specification.

The device, the subject of this invention is intended to fulfil all of the requirements of an ordinary quoin, and to have in addition thereto a means for retaining it in position even when the form in which the quoin is inserted is subjected to continued and ac tive operation and vibration.

The principal object of the invention is to provide a means for retaining a quoin in a lock position, and in the construction of our device we have provided that it may be employed with an ordinary quoin and as an addition thereto or that a quoin having our improvements may be a separate and distinct article of manufacture.

The following is what we consider a good mean of carrying out our invention and the accompanying drawings should be referred to for a complete understanding of the specification which follows.

Tn the drawings Figure 1 is a plan view of a quoin constructed according to our invention.

Fig. 2 is a plan view of a quoin having our device as a detachable part.

Fig. 3 is a side elevation of a part shown in Fi g. 2.

Similar reference numerals indicate like parts in all of the figures where they appear.

The device called a printers quoin is formed of two pieces, as indicated at 1 and 2. These parts are similar in every respect, and each is provided with an inclining surface 3 or 4 projecting from which is a rib 5 or 6.

The ribs project from each piece of the quoin, and in the opposite and enlarged portion'? or 8 of each piece a slot or groove is provided which receives the projections 5 or 6 of the other member.

The parts 1 and 2 are similar, and in operation two such pieces are used to make a complete quoin. and in each part 1 or 2 is provided a series of teeth or serrations 9 and 10 which are engaged by an operating key to cause the parts to ride one upon the other, and as the parts ride on an inclined surface, when they are moved one upon the other the distance between the outer faces of the two parts will .be increased, and byrthis increase the locking of a form [by means of the quoin is accomplished.

In. the enlarged portion 8 of the member 1 we insert a pin 11 which maybe an eye or hook, and into this hook or member 11, we engage one end of a spring 12. spring 12 is short and consists of few turns of spring wire. One end of the spring-is provided withthe loop described which engages the pin or hook 11, and the other end is turned to form' a plurality of eyes or rings 13.

Secured in the enlarged portion 7 of the other part of the quoin is a pin 14., which is adapted to engage any one of the eyes 13. The operation of this device is as follows:

The eye 13 is disengaged from the pin 14:, and by means of the ordinary tool the quoin is secured in position, locking a form, and when the quoin is tight and the form securely held the spring 12 is stretched until one of the eyes 13 can be securely engaged upon the pin 14. The form is now ready for use, and it will be found that any vibration that might occur will allow the spring 12 to tighten the quoin in position in the form for the reason that the spring will urge the parts of the quoin one upon the other. The quoin cannot become loosened until the spring is intentionally disengaged from the pin 13 or the hook 11 or both.

It is possible that some would desire to use our device with the quoins now in use, and that without change to accomplish this we provide two blocks 16 and 17. The one provided with a book 18, and the other with a pin 19. The spring 20 is constructed similar to the spring 12, and each of the blocks is provided with a groove 21 which will engage upon the projections 5 or 6 of the quoin.

In operating this device the quoin is set. and then the blocks 16 and 17 placed in position and the spring 20 stretched between the blocks. the blocks being arranged as shown in Fig. 2 one adjacent to each of the larger ends of the quoin members.

In this construction pins may be fitted in each of the blocks 16 and 17 or lugs may be formed integral therewith.

T he

" Parts of our device may be used without the whole, the shape or construction of the spring may be changed, and other modifications may be made within the scope of the appended claims without departing from the principle or sacrificing the advantages of the invention. r i

Having carefully and fully described our invention what we claim and desire to secure by Letters Patent is 1. A printers quoin -in two separable parts independently movable, and a spring arranged parallel and exterior to said parts to urge a relative movement thereof and means for temporarily securing said spring to said parts;

2. A printers quoin in two parts each having an enlarged portion, an engaging Copies of this patent may be obtained for having an eye secured to one of said parts, and a plurality of loops adapted to be temporarily engaged upon the other of said parts, said spring urging said parts upon each other.

4:. A printers quoin in two parts, an enlarged portion at one end of each part, a spring having an eye and a plurality of loops formed integral therewith, a pin arranged in each of said enlarged portions and adapted to engage said eye and one of said loops to retain said spring under tension longitudinally of said quoin, all combined for joint operation as and for the purpose set forth.
